Question 1102168: Suppose that the weight (in pounds) of an airplane is a linear function of the amount of fuel (in gallons) in its tank. When carrying 18 gallons of fuel, the airplane weighs 1999 pounds. When carrying 50 gallons of fuel, it weighs
2175 pounds. How much does the airplane weigh if it is carrying 60 gallons of fuel?

Question 1103082: Hi.
My question is related to my project:
F is a stable matrix (all eigenvalues are less than 1)
(F+G*K) is another stable matrix.
B is a positive semi definite matrix.
Q_i = [(F+GK)^i - F^i ] B [(F+GK)^i - F^i ]^T
Here is the equation:
Trace(Q_i) = [ Trace(S_i) ]^2.
Whats the best approximation of S_i in terms of F,B,G and K.
Thanks a lot
Navid
